EYELETING-MACHIN E.

, Application filed August 28, 1909.

To all whom it may concern:

Be it known that I, LEWIS F. WEBER, a citizen of the United States ofAmerica, residing at Frankfort on the-Main, Germany, have inventedcertain Improvements in Eyeleting Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to machines for setting fasteners, such aseyelets, lacing hooks and the like, in the uppers of boots and shoes,and relates particularly to devices whereby the work may be held firmlyduring the setting operation of the machine.

Heretofore in eyeleting closed uppersit has been diflicultt'o holdthework during the setting of the-lowest eyelet in'each quarter for the:reason that the junctureojf the vamp, tongue and quarter'sforms a bunchor thick part win the location where the'fpresser foot should engage theworkL'fThis thick part constitutes an obstruction' which it isdifficult' to pass under a presser foot'of the usual construction and sointerferes'with the setting of an eyelet in the required close proximityto the vamp. Even if the thick part is fed underthe presser foot-itaffords an uneven and restricted bearing for the latter with the resultthat the/work is liable to become displaced or twisted in the machineand injured by the punch or sets.

With these conditions in view it is an ob ject of the present inve'ntionto provide a work holding device which shall engage the work over aconsiderable area, thus preventing displacement thereof, the'locationand arrangement of said device being such as to avoid the thickportionin the closed upper and permit feeding the upper to the setswithout obstruction.

In feeding a right quarter to the sets the thick portion of the upper,mentioned above, falls at the left ofthe setting position, while indealing with a leftquarter the thick portion is upon the right side ofthis point.

An important feature of my invention consists in the provision of a workholding mechanism in which the right quarter is held and guided by amember located upon the ri ht side of the'setting position and the le tquarter by a member located upon the left side.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Serial No. 515,049.

A preferred embodiment of my invention comprises a presser footconsisting of two pivotally mounted parts either of which maybe moved tooperative or inoperative positions and locked in either of saidpositions; The operative position of one part is on the right side ofthe setting position whereby it is afforded an extensive bearing on theuneyeleted portion of the right upper and the thick portion of the upperlies beyond this part and moves away from it dur ing the settingoperation. On the other hand the operative position of the second partof the presser foot is on the left side of the setting position wherebythe left quarter is eyeleted with equal convenience.

As herein shown the two parts of the presser foot are so mounted thatone may be moved without effecting the'position of the other. To thisend the parts are journaled one above another to turn about a verticalaxis, the shank of the longer part being offset from its work engagingend so as to clear the shank of the shorter part." An advantage of thisconstruction is that both parts may be moved into inoperative positionsin the same verticalplane and therefore occupy, in inoperative position,a location more remote from setting position and more out of the way ofthe work than would be the case if the two partswere connected. Moreoverthe independent mounting of each part tends to improve its bearing uponthe work when in operative position.

These and other features of my invention will 'be best understood andappreciated from the following description of one embodiment thereof,selected for purposes of illustration and shown in the accompanyingdrawings, in which,

Figure l is a front elevation of the work holding mechanism showing theupper set and work table, and Fig. 2 is a plan view of the same.

The work table 12 is slotted at 14 to receive an anvil block upon whichthe punch 10 cuts and to permit the passage of the lower set for settingthe eyelets in the work. As shown herein the punch 10 is provided with aclenching or upsetting shoulder and cooperates with the lower settingdie in clenching the barrel of a fastener upon the work. At the rear ofthe work table and mounted for vertical reciprocation upon anyconvenient part of the machine is the rod 2 carrying upon its upper endthe journal member 3. The presser foot consists of two parts 4: and 5'which are mounted to turn upon the journal member 3. Each part of thepresser foot has a portion adapted for use with one quarter of a closedupper and is provided with a rearwardly extending portion 8 providedwith a spring pressed plunger 6 cooperating with notches in the journalmember 3 to hold the parts of the presser foot in one of twopredetermined positions. For example, the part 4 is shown in itsoperative position by the fulllines in Fig. 2 in which position it holdsand guides a left quarter, permitting the closed upper to be moved asfar to the left'as may be necessary for setting the lowest eyelet nearthe vamp. The dotted lines in Fig. 2 show the part 4 in its inoperativeposition where it is entirely clear of the work and which position itoccupies while the other part 5 of the presser foot is operative.

It will be apparent from Fig. 1 that the work engaging ends of thepresser foot parts lie in the same horizontal plane while the shank ofthe longer part 4 is bent sharply upwardly so that it may swing over theshank of the shorter part 5 without interference.

For retracting the spring pressed plungers 6 the levers 7 are provided,each being pivoted upon the portion 8 of a presser foot part and havingits end so located as tobe within convenient reach of the operator.

Preferably the two parts ofthe pressing members 4 and 5 which areintended toengage the work are conformed to the shape of the slot in thework table, each part extending some distance along the side of the slotand across one end thereof so as to en gage the work over a considerablearea.

The rod 2 which carries thetwo parts of the presser foot has suitableconnections (not shown) with mechanism for intermittently lifting-it topermit the work to be fed and also with a treadle whereby the presserfoot may be raised for the insertion of the work, all of which mechanismis well known in the art and requires no particular description in thisplace. i

The operation of the work holding device will be clear from theforegoing description. In practice the two ,quarters are eyeleted withtheir inside uppermost, the part 5 of the presser foot being operativeduring the eyeletting of the right quarter and being moved by theoperator into its inoperative position when the left quarter is to beeyeletted and vice versa. In moving one of the presser foot parts tooperative or inoperative position it is necessary only to press theappropriate finger lever 7 and then swing the presser foot part towardthe desired position. l/V hen this is reached the spring locking pinenters the propernotch in the journal member and so automatically locksthe part in position.

Having described my invention and illustrated a preferred embodimentthereof, what I claim as new and desire to secure by Letters Patent isl. A machine of the class described having, in combination, fastenersetting devices, 'a'work supporting table, and a presser foot having twoindependently movable bearing members either of which may be moved intoan noperative position out of engagement with the work, one of themembers being adapted for use with one quarter of an upper and the othermember with the oppo'site quarter.
